Abstract: Benzil-benzilic acid rearrangement under phase-transfer conditions has been studied. No rearrangement was observed using 50% KOH solution-tolene and benzyltriethylammonium chloride as the catalyst with or without sonication. Considerable acceleration of the rearrangement by ultrasound was observed at the solid-liquid phase-transfer conditions, especially when a horn technique was used or when the powdered KOH was used.
